RIHANNA & CHRIS

"We are very good friends," Rihanna said of Brown after pictures of them smooching surfaced. It wasn't the first time the two were caught canoodling: In February, they escaped to Jamaica for a steamy vacation. And this May, Brown celebrated his 19th birthday with a kiss from his lady in Manhattan. So, why not just come clean about their relationship? "Sometimes you just need your privacy," she said in a radio interview. "But it comes with the territory. There's no privacy when you are out in the public."
